Comment:

 Most likely you have multiple network cards and the default route does not
 match the interface you need to use for the multicast group. You need to
 either:

 - get your system administrator to add a route for the multicast group
 that uses the correct device; or

 - change your code to use the two-argument join_group constructor that
 lets you specify the interface.

 Most likely the Java application does the latter. As multicast group
 subscriptions are system-wide, this makes your application work too.
 However, the first option is IMHO the preferred approach.
